Thanks for the hints. I've read through all I could find and tried to
provide some help.

I'm kind of confused, most of them enable CONFIG_X86_SYSFB (which is
'n' by default) but don't read the help text. I did my best to tell
people that this option requires CONFIG_FB_SIMPLE, but if you don't
read the help-text you won't notice that. Don't know what to do about
that..

Thanks
David
